In the fitted state, the inlet 12 on the bottom surface is located at a position slightly higher than the lower surface of the fitting groove 2. , So that water in the water tank V can easily enter. Also,
The outlet 13 of the water intake guide G is fitted and connected to the inflow port 3 of the dung collection case C, and the water flowing into the water intake guide G is guided into the dung collection case C.

The feces storage bag B is constructed by attaching an edge frame 16 to the upper open end of a vertically long bag body 15 made of a mesh material, and removably fitting a lid 17 to the edge frame 16.
An upper part of one side of the bag 15 is provided with a feces intake 18. The feces storage bag B can be detachably stored in the feces collecting case C from the insertion port 8, and the feces collecting port C is fitted to the outlet 13 of the water guide G to fit the feces collecting case C. The feces storage bag B and the water intake guide G can be integrally connected via the same, and the feces storage bag B cannot be removed from the feces collection case C unless the water intake guide G is removed.

A pair of mounting pieces 21 having connection holes 20 are integrally formed on the upper surface of the lid 17, and the handle H is detachably connected to the mounting pieces 21.

The handle H is provided with an outer 25 having a vertically long inner 24 having a fork-shaped mounting portion 23 fixed to the lower end thereof.
The inner 24 and the outer 25 are frictionally held at appropriate expansion and contraction positions by uneven engagement between their sliding surfaces. Hawk-shaped mounting part 23
A pair of engaging pins 26 protrude from the opposing inner surfaces of the connecting holes 2 of the lid 17.
The handle H can be connected to the feces storage bag B by fitting the handle H into the bag 0. A hook 27 is attached to the upper end of the outer 25, and the hook 27 can be engaged with and disengaged from the suction pipe P (see FIG. 1).

The suction pipe P includes an inner pipe 29 and an outer pipe 30 which are frictionally fitted to each other so as to be extendable and contractible, and an elbow-shaped ejection beak 31 is connected to an upper end of the outer pipe 30. An air pipe 32 is inserted into the suction pipe P from its upper end, and
An airstone 33 is connected to a lower end of the suction pipe P, and a discharge port of an air pump Pu is connected to an outer end of the air pipe 32 extending above the suction pipe P. As shown in FIGS. 2, 3, and 7, the lower end of the suction pipe P is connected to the outflow port 6 of the dung collection case C. A suction cup 34 is attached for suction.

Next, the operation of this embodiment will be described.

As shown in FIGS. 1 to 5, a dung collection case C is installed at the bottom of a water tank V, and a dung storage bag B is inserted thereinto, and the lower end of a suction pipe P is connected to an outlet 6. Then, the feces collector according to the present invention is set in the water tank B. Here, if the air pump Pu is operated, the pressure air is supplied to the air pipe 32.
Through the airstone 33 and into the suction pipe P,
Due to the suction airflow generated in the pipe P, the water in the water tank B is sucked into the dung collection case C together with the dung, remaining bait, dust and the like. That is, as shown by arrows in FIGS. 2 to 5, water containing feces, bait, dust, and the like remaining at the bottom of the water tank B is:
It rises in the water intake guide G from the inlet 12 and flows into the feces storage bag B through the outlet 13 and the feces intake 18. In the dung storage bag B, dung, remaining bait, dust and the like are stored, and water separated and filtered therefrom is collected in the dung storage bag B made of mesh material.
Then, the water enters the dung collection case C, passes through the outlet 6 and rises in the suction pipe P, and is ejected from the ejection beak 31 into the water tank V. As described above, by allowing the water in the water tank V to flow through the feces collector, the feces, residual food, dust, and the like remaining and deposited in the water tank V are automatically collected in the feces storage bag B. be able to.

When a certain amount of feces, remaining bait, dust and the like are stored in the feces storage bag B, the operation of the air pump Pu is stopped, then the water intake guide G is removed from the feces collection case C, and the handle H is moved upward. By pulling, as shown in FIG. 7, the feces storage bag B can be pulled out of the feces collecting case C and taken out of the water tank V.

When collecting feces, remaining bait, dust and the like again, the feces storage bag B is inserted and stored in the feces collecting case C,
After the water intake guide G is fitted to the feces collection case C and the assembling of the feces collector is completed, the air pump Pu is operated.

However, in the above-mentioned work of collecting feces, bait, dust and the like, the suction pipe P and the handle H are continuously adjusted in length according to the depth of the water tank V. In addition, when pulling out the feces storage bag B from the water tank V, it is not necessary to touch the feces storage bag B. Further, the feces storage bag B can be fixed to the feces collecting case C by the water collecting guide G, and does not come off from the feces collecting case C unless the water collecting guide G is removed.

Next, a second embodiment of the present invention will be described with reference to FIG.

FIG. 8 is a cross-sectional view of a feces collector according to a second embodiment of the present invention. In the figure, the same elements as those in the first embodiment are denoted by the same reference numerals. The second embodiment differs from the first embodiment in the shape of the filtration case C. That is, the filtration case C is formed in a hollow triangular prism shape, and the rear wall 4 is provided with a pair of inclined walls 4 ′ having an included angle θ of about 90 ° in plan view. 'Is attached to the suction cup 10. A recess 5 having a U-shaped cross section for accommodating the suction pipe P is formed in the central flat wall 4 ″ between the inclined walls 4 ′.

In the second embodiment, however, FIG.
As shown in the figure, the feces collector according to the present invention is suitable for being installed at the corner of the water tank V, and has the same effect as that of the first embodiment.

In the first and second embodiments, a conventional well-known bottom filtration device may be connected to the inflow port 3 opened to the dung collection case C.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments, and various embodiments are possible within the scope of the present invention. For example, in the above-described embodiment, the dung collection case is formed in a quadrangular prism shape, a triangular prism shape, but it may be formed in a columnar shape or another shape, and for sucking up water in the dung collection case, Another pump such as a submersible pump may be used instead of the air pump.

[0026]

As described above, according to the first aspect of the present invention, it is possible to automatically and efficiently collect and remove feces, residual food, garbage, etc., which settle in the water tank. Water quality can be prevented from deteriorating due to conversion. In addition, the feces storage bag that stores the collected feces, remaining bait, garbage, and the like can be taken out without touching the feces collecting case in the water tank, thereby improving the efficiency of the collection operation.

[0027] In order to achieve the above object, the present invention is applied to claim 2 of the present invention.
According to the invention described in the description, in addition to the same effect as the invention described in claim 1, the attachment of the feces storage bag to the feces collection case is facilitated, and the feces storage bag is firmly attached to the feces collection case by the water guide. Can be installed.
